Abstract
An automated apparatus can provide pre-analytical processing of samples, racking and forwarding to an adjacent analyzer for analysis. The apparatus may have a controller that implements an auto-learn process to teach robotic handlers the locations within the workspace(s) of the apparatus. A robotic sample handler may include a sensor configured to generate a detection signal when in a near vicinity of a fiducial beacon in the workspace of the apparatus for biological sample preparation, preprocessing and/or diagnostic assay performed by one or more analyzers of the automated apparatus. The controller may control the robotic sample handler to conduct a search pattern so that a location of the fiducial beacon may be detected and thereafter calculated to obtain a more accurate location of the beacon. The calculated positions may then serve as a basis for the controlled movement of samples by the robot to and from locations of the workspace.
